Gravitational collapse of depletion-induced colloidal gels.

Soft matter

Harich R, Blythe TW, Hermes M, Zaccarelli E, Sederman AJ, Gladden LF, Poon WC.
PMID: 27001686
Soft Matter. 2016 May 11;12(19):4300-8. doi: 10.1039/c5sm02651b.

We study the ageing and ultimate gravitational collapse of colloidal gels in which the interparticle attraction is induced by non-adsorbing polymers via the depletion effect. The gels are formed through arrested spinodal decomposition, whereby the dense phase arrests into...

Comparison of Approaches in Estimating Interaction and Quadratic Effects of Latent Variables.

Multivariate behavioral research

Lee SY, Song XY, Poon WY.
PMID: 26759934
Multivariate Behav Res. 2004 Jan 01;39(1):37-67. doi: 10.1207/s15327906mbr3901_2.

Various approaches using the maximum likelihood (ML) option of the LISREL program and products of indicators have been proposed to analyze structural equation models with non-linear latent effects on the basis of Kenny and Judd's formulation. Recently, some methods...

Quant Imaging Med Surg. 2013 Dec;3(6):316-26. doi: 10.3978/j.issn.2223-4292.2013.12.08.

Current widespread use of cross-sectional imaging has led to exponential rise in detection of solitary pulmonary nodules (SPNs). Whilst large numbers of these are benign 'incidentalomas', lung cancers presenting as SPNs are often early disease, which have good prognosis....

We report a detailed experimental study of the kinetics of separation into coexisting gas, liquid, and crystal phases in a colloid-polymer mixture. Distinct kinetic regimes are identified, and interpreted in terms of the underlying "free-energy landscape" of the system.

Polymethylmethacrylate (PMMA) colloids sterically stabilized by a layer of chemically grafted poly-12-hydroxystearic (PHSA) are widely used in experiments as model hard spheres. However, due to the coating, the interaction between particles is slightly soft. Here we report a numerical...
